Patented Mar. 3, 1931 UNITED STATES PATENT OFFICE EMORY GLENN SIMPSON AND FRANK M. EDGAR, OF DETROIT, MICHIGAN, ASSIGNORS TO TERNSTEDT MANUFACTURING COMPANY, OF DETROIT, MICHIGAN, A COBPORA-\ r1011 or MICHIGAN ADJUSTABLE STRUCTURE FOR SEATS Application filed December 21, 1928. Serial No. 327,523.

This invention relates to adjustable structure for seats.

In the manufacture of adjustable structure for automobile seats consisting of track and slide members adapted to slidably engage in order to ad ust the seat, 1t has always been necessary in order to obtain a nicety of en-.

gagement between the slide member and the track that both the track member and the slide member be very accurately fitted with a consequent substantial increase in production costs. If the track and slide members are not very carefully fitted, a nicety of slidable engagement between the track and slide members is impossible and chattering and rattling results which is most undesirable in automobile seat structure. In order to obtain a nicety of engagement between the track and slide members without this very careful manufacturing or machining, we have provided a distortable material which we insert between the upper and lower slide members. This distortable material in the assembly of the track and slide members permits adjustment of the members and a nicety of fit even though the track and slide members have not been accurately formed by stamping, machining or otherwlse. I

. In the drawings: r

Fig. 1 is a top plan view of the adjustable track structure with parts brokenaway in order to show the position of the distortable material between the upper and lower slide members.

. Fig. 2 is .a side elevation of track' structure. o 7 Fig.--3 is a section along theline 3-3 of Fig. 2.

the adjustable Fig, 4 isa section along the line of- Fig. 2.

Referringmore particularly to the drawings,-the seat 'frame may be designated 1. The seat is supported from the floor, which maybe referenced 2, by'the seat support which consists of a trackmember 3 having a flange 4 which is adapted to slidably engage the upper slide member 6 and the lower slide member 5 in a channel created by the cooperation of the upper and lower slide members.

"- Between the upper and lower-slide members,

we have placed a strip of distortable material 7. The upper and lower slide members are fixed to the seat frame and to each other by any suitable means such as the screws which are referenced 8.

An adjusting mechanism generally referenced 9 is provided, and by turning the screw member 10 a thrust action is created in the lever arms 11 which causes relative movement screws 8 the slide members can be brought 4 closer together or farther apart.

-From the foregoing description it is seen that we have provided an adjustable track and slide structure-which allows-a nicety of sliding engagement between the track and slide members without chattering and rat- 7 tling', even though the track-and slide members are rough and not accurately machined or finished.

What we claim is:

1. In an adjustable seat structure, a'track, a slide -member, provided with upper and lower parts'movable toward and away from each other, means for efiecting said moveslida ly engage said track, and distortablc material between said parts of the slide mem-' her to allow relative movement between said parts to effect a' nicet of engagement be-" tween said track and s ide.

' 2. In an adjustable seat structure, a track, a slide member provided with opposed parts movable toward and away from each other,

means for effecting said movement, said op- "ment said uppewand lower parts adapted to posed parts adapted to slidably engage said track, and distortable material between said parts of the slide member to allow relative movement between said parts to eflect a.

nicety of engagement between said track and slide. a

3. In. an adjustable seat structure, a track having a flange, a slide comprising opposed members arranged to slidably engage the flange of the track and to move relative to each other, means for effecting relative movement of said members, and a strip of distortable material'between the parts of the said slide and offset from said flange which permits the said parts to be adjusted relative to each other to effect a nicety of engagement with the flange of the track.

In testimony whereof we have aflixed our signatures.
